What forum software do giant sites use?

Answer:
Many large forum communities use vBulletin. It has been tested and proven to scale very well.

Other communities may use Invision Power Board, as it has many free skins and mods, and is easier to control than vBulletin. However, vBulletin is more powerful, and using it, you will have more control over the forum.


Also many free software such as SMF, phpBB and YaBB are also used, with great success over the paid alternatives.
